Does kopete do sound streaming? Oddly enough, I can do video streaming, but no sound, and I don't see a place to configure the sound devices either (as e.g. in skype). I know for video I had to have jasper, do I need some plugin for sound too? Incidentally, like others on this list I was having problems with configuring the microphone in skype (I could hear the incoming sound, but they could not hear me). What I did was to open volume control (in gnome, but I imagine it would be similar in kde) -> edit -> preferences, then check just about every capture item (e.g. line-in capture, microphone capture, etc.) although I believe the microphone capture is really the important one. Then, under the Playback panel, the microphone slider must be on. Under the Recording tab, the capture slider must be on. Under the Switches tab, I had to have Microphone Capture (and Mic Boost) checked, and under Options, the appropriate microphone must be selected (I can choose between Mic1 and Mic2; when the correct one is selected, you can hear your own voice into the speakers, when talking into the microphone). Now if skype could do video streaming... Some suggested (and others agreed) that alsa is a big mess, but I just don't see why. It begins to make sense when you read the documentation - at least the FAQ. Just poke around in /proc/asound. And even if you don't know anything about the internals of alsa (like me), all it takes is to fiddle a little bit with volume control to turn on the appropriate capture devices.
